To @ZZ whom, t may concern.-

Be it known that JOHANNES HAAG, of Augsburg, in the Kingdom of Bavaria and Empire of Germany, have invented certain new and useful Improvements in Steam and Hot-Tater Radiators, of which thefollowing is a specification.

This invention has reference to\an improved steam and hot -water radiator, which combines to some extent the advantages of heating lby steam and hot water in one system, and the invention consists of a closed hotwater reservoir having a central longitudinal opening communicating with air-openings in the base ofthe reservoir, a steam-coil located in the hot-water reservoir and connected with a steam-supply pipe, and with a valved pipe for drawing off the water of condensation.

In the accompanying drawings, Figure l represents a front elevation of my improved steam and hot-water radiator. Fig. 2 is a vertical central section of the same on line x x, Fig. 3, and Fig. 8 is a horizontal section on line y y, Fig. 2.

Similar letters of reference indicate corresponding parts. v

In the drawings, A represents a closed hotwater reservoir, which is preferably of cylindrical shape, and supported on a base, A, having screened openings a a, for the admission of air. The base Ais prefe 1ably made of castiron and riveted to the bottom B of the reservoir A. The bottom B is made of cast-iron, with concentric fiangcs b b cast integral therewith. The reservoir A has a central open tube, c', that extends longitl'idinally through the same, for the passage of air. The outer wall, C, of the reservoir A is tightly secured to the outer flange, b, of the bottom B, and the interior wall, C, is attached to theiiange 7) of the same. Between the outer and inner walls C C is formed an annular space, that is closed at the top by a ring-shaped top plate, B, to which the walls C C of the reservoir are applied in the same manner as to the bottom B.

is filled to about half its height with water The space between the two cylinders C O/ through an opening in the top plate, B, said opening being closed by a screw-plug, B2.

Through this opening water is supplied from, time to time to the reservoir, as required, to compensate for small losses by evaporation. Vhenever it is desirable to remove the water,

it can be done through an opening, g, arranged in the bottom B'. by a screw-plug. A is heated by a steam-coil, D, which is located in the lower part of the reservoir, and connected to a steam-supply pipe, d, at its upper end, which passes through an opening in the top plate. The lower end of the coilD is connected, by a pipe, d, that passes through an opening in the bottom B, to a valved pipe, di, which is again yconnected with a vertical pipe, d3, through which the water of condensation is conducted off. As the shape of the worm gives sufficient elasticity to the metal This opening is also closed to provide for expansion and contraction, a

stuffing-box is not needed\at the points where the steam-pipes enter and leave the reservoir. The steam, as it passes through the coil D, heats the surrounding water and raises it to The water in the reservoir n the boiling-point, thus lling the space in the,

upper part of the reservoir with low-pressure steam, while the steam in the coil D is partly condensed and conducted off.

The'heating of the air in the room which is supplied with a radiator of thisconstruction takes 'place in two ways: iirst, by radiation from the outer surface o f the reservoir, and by convection, as the cold air. venters through the screened openings in the base A', becomes heated in contact with the interior surface of the reservoir, andV passes out at the top, thereby keeping up a regular circulationv of air through the center of the reservoir, as indicated by arrows in Fig. 2. Vhenever it is desirable to diminish the heat, it is only :necessary to` close partly or entirely the valve of pipe d?, whereby the coil D is partly or entirely filled with water produced by the condensation ofthe steam, so that the heating action of the same on the water in the reservoir is partly or entirely interrupted. By opening the valved pipe di, the heating action of the radiator is resumed.

Having thus described my iuven tion, I claim as new and desire to secure by Letters Patent- A Combined steam and hot-Water radiator, In testimony that I claim the foregoing as Consisting of a hot-Water` reservoir having a my invention .I have'signed my name in proscontml opening, 2t supporting-basehaving airence of two subscribing witnesses. supply openings, a steam-coil located in the 5 reservoir, a pipe to supply steam to the coil, Vitnesses:
